Overview

Holley EFI Gen V LT Single Plane Intake Manifolds

Holley EFI Gen V LT single plane intake manifolds are designed with an optimized runner layout and a constant cross-sectional area, resulting in a broad torque curve with the best vehicle performance from 2,500 to 7,000 rpm. The single-plane design provides the lowest throttle body flange height possible, while providing maximum performance all the way to 7,000 rpm. The cast aluminum construction makes these manifolds great choices for centrifugal blowers, turbochargers, or NOS applications. They are sold for pre-emissions control applications only and will not accept stock components and hardware. Available in two finishes, choose the one you prefer.
